SCANNING FEATURES
Scan Mode
Selects the scan operating mode for the reader. Selections are:
Trigger Single:
When the trigger is pulled, scanning is activated until one of the follow-
ing occurs:
•Stand Mode/Object Detection has elapsed
•a label has been read
•the trigger is released
This mode is associated with typical handheld reader operation: when the trigger is
pulled, scanning starts and the product scans until the trigger is released, or a label is
read, or the maximum Stand Mode/Object Detection has elapsed.
Trigger Hold Multiple :
When the trigger is pulled, scanning starts and the product
scans until the trigger is released or Stand Mode/Object Detection has elapsed. Reading
a label does not disable scanning. Double Read Timeout prevents undesired multiple
reads of the same label while in this mode.
Trigger Pulse Multiple:
When the trigger is pulled, continuous scanning is activated
until Stand Mode/Object Detection has elapsed or the trigger has been released and
pulled again. Double Read Timeout prevents undesired multiple reads of the same label
while in this mode.
Flashing:
The reader flashes
1
on and off regardless of the trigger status. Flash rate is
controlled by Flash On Time and Flash Off Time. When Flash is ON the reader reads con-
tinuously. When Flash is OFF scanning is deactivated.
Always On:
No trigger pull is required to read a bar code. Scanning is continually on.
Double Read Timeout prevents undesired multiple reads of the same label while in this
mode.
Stand Mode/Object Detection:
No trigger pull is required to read a bar code. Scanning
turns on automatically when an item is placed in reader's field of view. While in a stand
watch state, the reader illumination LED goes from dim to maximum bright.
